To all whom it may concern:

, Be it known that I, HARRY G. COLLIER, a

citizen ofi-the gUnited States, residing at Muncie, in the county of"Delaware and reduced to a minimum and wear and tear on the lockingmeans is obviated.

My invention is embodied in, and the purposes thereof are accomplishedby the new construction. combination, and arrangement of parts shown inthe accompanying drawmgs. The several parts of the 1nvent1on, as

they appear in the difierent views in the drawings. are identified bysimilar characters of reference applied thereto.

Figure l is a side view of a-portion of a freight car, same beingequipped with my invention. Fig. 2 is an enlarged'view of a frontalportion of the car door, a portion thereof being; broken away. Fig.3 isa detail view of the upper portion of the lockbar. Fig. 4 is an enlargedview of the stop block and connected parts, and Fig. 5 is a transversesectional view taken on the line 55 in Fig. 4:, and as seen inthedirection indicated by the arrow.

The car door, carried by suitable hangers s and roller devices shown, iscapable of being easily moved, and is properly retained againstvibration and displacement.

At the frontal edgeof the door opening is secured a housing A. Withinthis housing and between suitable guide ways B is disposed a lock bar C.This lock bar is sustained yieldably at the raised position shown. Themeans for so sustaining this lock bar consists of a spring D whose lower.end is secured to a clip E fastened to the car frame, and whose upperend is secured to a clip C that is fastened to the lock bar C.

Bv means of a lever F connected to the bottom of the lock bar and whichis fulcrumed to the block G, the lock bar may be readily Specificationof Letters Patent.

lowered. Projecting from the front of the 'lockbar is a stud C whichextendsthrough a ,vertical slot A of the housing The function'of this studwill be presently referred to. r

Countersunk'in the rear ate a all; rental edge of the door are latchlugs H. Each of these latch lugs has the nose H and the-inclined face Hand the recess B. These partsof the latch lugscorre'spond'respee tivelyto the recesses G the'inclined faces C and the teeth C? of the lockbarC. It will be observedthai; therelativepositions of the severalparts'are'such (see Fig. 3)

that although the lock bar and the latch lugs are retained immovable,coengagement,

7 their cooperative. action is such that when the lock bar is lowered,the tooth C leaves the recess H", and the face C at the suitable handleand moved orwardly. The lever F 1s then depressed. When the door hasbeen moved completely to the closed position" the noses H of the latchlugs will have passed the teeth C? of thelock bar. The lever F is thenreleased. By the action of the spring D the lock bar is returned to thenormal raised position. The teeth C are now in'engagement with therecesses H and the door is latched at closed position.

Secured to the outer face of the housing A is a stop block K having anaperture K in which the stud C is free to move vertically. At a locationimmediately below the position of the stud C when the lock bar G is atthe raised and normal position shown, a transverse bore K passes throughthe stop block K. A check L that occupies the said bore is retained by aleafspring L normally at position "removed from the track of the stud C.Near the end of the check pin is a hole L In a casing M that is securedto the outer face of the door at its frontal edge, a detent N isretained.

The lock bar being thus locked the door is bears against then sealed bythe insertion of a wire 2 its .ily and e ectiveli ends being broughttogether and secured by the usual leaden seal 3.

By the foregoing construction, combination and arrangement of parts, adoor is provided which is capable of being easily moved to closedosition, securely latched, and easlocked. By the latching means shown, atendency of the door to vibrate is overcome and the retention of thedoor at the securely closed position is assured. There being nopossibility of strain at the lock, the difiiculty heretofore experienced where the seal, is broken and the car hasbecomeun1ocked,isovercome. More over, there is the facility in the opening ofthe door. With the breaking of the seal and the removal of the wire 2,the detent L moves to retracted position. By a depressing then of thehand lever F there is caused.

the contact of the faces C and H and the disenga ement of the tooth Cfrom the recesses The action of the spring N being then free, a rearwardimpulse is imparted to the door and it rolls to open position.

What I claim as my invention, and desire to be secured by LettersPatent, is

1. Afastener for car doors comprising a vertical lock bar having thetooth and recess, means to sustain the lock bar yieldably at raisedposition, a latch lug carried by the door and that has a tooth andrecess to engage the tooth and recess of the lock bar, and'there beinginclined meeting faces on the lock bar and latch lug so cooperativelyadapted that when the lock bar is depressed the teeth and recesses aredisen aged and the door is forced from the close position.
